The portable cement mortar stirring machine can overcome the problem that cement dry powder has high liability of pseudo-coagulation after absorbing water, and ensures smooth stirring and uniform material stirring. The portable stirring machine is very convenient for carrying and use, and can shorten stirring time, save manpower and reduce cost when being applied in the field of construction engineering. In addition, the stirring machine has small vibration and good stability during use.

Description

A kind of portable cement plaster blender

Technical field

The utility model relates to the used mixer of mixing of a kind of cement or mortar.

Background technology

In the prior art, cement plaster blender mainly adopts modal agitator type, i.e. the agitator of shaft that vertically extends and the slurry formula stirring vane formation that is installed in a certain height of shaft (being generally lower end position).Existing mixer has the following disadvantages:

When 1, adopting the mixer of this agitator to be used for cement mortar to mix, can't allow the dry mixing mixing of cement mortar dry powder or dry powder and water under different proportion, all can stir easily; And, can't overcome cement powder and absorb false condensing (setting and harden) problem that is prone in the hydration process of moisture content, cause stirring and can't carry out smoothly;

2, existing mixer is to be fixedly installed in the agitator and uses, and uses and carry inconvenience;

3, existing mixer particularly when running into false condensation problem, produces very big vibration in whipping process, causes be connected between motor and the shaft loosening easily and breaks away from, and influences the service life of agitator.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of improved cement plaster blender is provided.

For solving above technical problem, the utility model is taked following technical scheme:

A kind of portable cement plaster blender, it comprises portable electric machine and the agitator that is driven by the portable electric machine, the periphery of the bottom that described agitator comprises shaft that the upper end is connected with the portable electric machine, be looped around shaft and along the helical blade of the direction of axis line extension of shaft and be set in outside the shaft and by the hold cover of bearing fixing on the top of shaft.

According to a preferred aspect of the present utility model, described agitator also comprises the outstanding lever of holding the cover outer surface, and the length direction of this lever is perpendicular to the direction of axis line of shaft.

According to further embodiment of the present utility model, removably connect mutually between described shaft and the portable electric machine, specifically can be the mode of being spirally connected, promptly establish public tooth in motor and the shaft, establish female tooth on another; In addition, can also utilize the chuck of the portable electric machine shaft that is fixedly clamped.

Preferably, described helical blade welds mutually with shaft.The length ratio of helical blade and shaft is 1: 2～4.Usually, the internal diameter of described helical blade is 10～20 millimeters, and external diameter is 70～80 millimeters.The pitch of helical blade is 0.8～1.2 times of its external diameter.

According to a preferred version of the present utility model: the lower end position of shaft is provided with described helical blade at least.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

1, agitator of the present utility model outside the lower, outer perimeter of shaft around the helical blade that extends along the shaft direction of axis line, when stirring, the vertical helical blade of rotation has the function of piercing, can overcome the false condensation problem that the cement powder suction is prone to, the assurance stirring is carried out smoothly and well material is stirred.

2, mixer of the present utility model is portable portable agitator, carries with easy to use and efficient is high, is applied in building engineering field, can shorten mixing time, saves manpower and reduces cost;

3, hold cover owing to outside shaft, being arranged with, then when mixer is worked, but both hands are held the handle and the described cover of holding of portable electric machine simultaneously, so, can improve the stability when stirring and prevent to stir axial skew, save manpower and the service life that prolongs agitator when stirring.

Description of drawings

The utility model is described in more detail below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is the perspective exploded view according to mixer of the present utility model;

Fig. 2 is the schematic perspective view according to agitator of the present utility model;

Wherein: 1, portable electric machine; 2, shaft; 3, helical blade; 10, chuck; 11, handle; 4, hold cover; 5, lever; 6, bearing.

The specific embodiment

As depicted in figs. 1 and 2, mainly form according to the portable portable mixer of present embodiment by portable electric machine 1 and agitator.Wherein, agitator specifically comprises shaft 2 that upper end and portable electric machine 1 chuck 10 by motor is connected, the periphery of the bottom that is looped around shaft 2 and the helical blade 3 that extends along the direction of axis line of shaft 2, is set in shaft 2 outside and is fixed on the holding cover 4, overlap 4 levers of fixedlying connected 5 with holding of top of shaft 2 by bearing 6.The length direction of lever 5 and shaft 2, the direction of axis line of holding cover 4 are vertical substantially.Welding mutually between the helical blade 3 of agitator and the shaft 2, the length of shaft 2 is about 750mm to 800mm, hold cover 4 upper end apart from the about 50mm in the upper end of shaft 2, and itself length is about 150mm, the length of the helical blade 3 of agitator is about 260mm.

The mixer of present embodiment has following characteristics:

1, the bottom of agitator is the helical blade form with the function of piercing, thereby when agitator drive motor during around the rotation of the axial line of shaft, helical blade 3 can stir material well and overcome false condensation problem;

2, mixer in use, a handle 11 that holds the portable electric machine, another holds lever 5, on the one hand, stability in the time of can improving mixer work prevents that the position of shaft 2 and helical blade 3 is offset, and prolongs the service life of agitator; On the other hand, can reduce to vibrate influence to the operator for example arm is numb and turn sour, save manpower, raise the efficiency.

More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
